Set R environment with rpy2:

Code

import rpy2.rinterface_lib.callbacks
import anndata2ri
import logging

from rpy2.robjects import pandas2ri
import rpy2.robjects as ro

sc.settings.verbosity = 0
rpy2.rinterface_lib.callbacks.logger.setLevel(logging.ERROR)

pandas2ri.activate()
anndata2ri.activate()

%load_ext rpy2.ipython

Set up of graphical parameters for Python plots:

Code

%matplotlib inline
sc.set_figure_params(dpi = 300, fontsize = 20)

cmap_up = sns.light_palette("red", as_cmap=True)
cmap_down = sns.light_palette("blue", as_cmap=True)
cmap_all = sns.light_palette("seagreen", as_cmap=True)

Set up of graphical parameters for R plots:

Code

default_units = 'in' 
default_res = 300
default_width = 10
default_height = 9

import rpy2
old_setup_graphics = rpy2.ipython.rmagic.RMagics.setup_graphics

def new_setup_graphics(self, args):
    if getattr(args, 'units') is not None:
        if args.units != default_units:

Here the cell were we inject the parameters using Quarto renderer:

Code

# Injected Parameters
N = 3

Code

# Injected Parameters
N = 6

Import R libraries:

Code

%%R
source('./../../../../utilities_folder/GO_helper.r')
loc <- './../../../../R_loc' # pointing to the renv environment

.libPaths(loc)

library('topGO')
library('org.Hs.eg.db')
library(dplyr)
library(ggplot2)

Set output folders:

Code

output_folder = './'
folder = './deg_in_cluster_tables/cluster_' + str(N) + '/'

import os

if not os.path.isdir(folder):
    os.makedirs(folder)

2 Load data

Here we load the anndata:

Code

GO2gene = load_object('./../../../../data/GO2gene_complete.pickle')

Here we load the dictionary that associates to each GO term its genes:

Code

adata = sc.read("1_All_Annotated_Triku.h5ad")
adata

3 Markers of cluster

We filter genes for the cluster under investigation based on the p-value adjusted that we then convert in -log(p-value adjusted):

Code

markers = sc.get.rank_genes_groups_df(adata, group=str(N))
intTable(markers, folder=folder, fileName = 'markers_cluster_before_filtering_' + str(N) + '.xlsx', save = True)

Code

markers = markers.set_index('names')
markers = markers[markers.pvals_adj < 0.01]
markers['FDR'] = markers['pvals_adj']
markers['-log10(FDR)'] = -np.log10(markers.pvals_adj)
markers = markers.replace(np.inf, markers[markers['-log10(FDR)'] != np.inf]['-log10(FDR)'].max())
